Study Notes
Software Processes
- Defined as a coherent set of activities involved in specifying, designing, implementing, and testing software systems.
- Encompasses the entire lifecycle of software development from initial concept to final deployment and maintenance.
Software Process Model
- Conceptual framework that provides an abstract representation of a software process.
- Offers perspectives on how processes can be structured and managed.
- Serves to facilitate understanding and communication of processes among stakeholders.
Software Processes Overview
- All software processes encompass four fundamental stages: Specification, Design and Implementation, Validation, and Evolution.
Specification
- Involves clearly defining the system's requirements and functionalities.
- Establishes what the system is expected to achieve based on customer needs.
Design and Implementation
- Focuses on organizing the system architecture and components.
- Involves the coding and construction of the software, transforming designs into a functioning product.
Validation
- Aims to ensure the software meets user expectations and requirements.
- Involves testing and verification methods to confirm that the system operates as intended.
Evolution
- Refers to the process of adapting the software in response to changing user demands or technological advances.
- Ensures the system remains relevant and functional over time, accommodating new features or modifications.
Agile Methods in Software Development
- Main Agile methodologies include Scrum, Lean, Extreme Programming (XP), Crystal, Kanban, Dynamic Systems Development Method (DSDM), and Feature-Driven Development (FDD).
Scrum Methodology
- A lightweight Agile framework managing iterative and incremental projects.
- Product owner creates a product backlog to prioritize system functionality.
Lean Software Development
- Focuses on effective value stream mapping to enhance customer value.
- Principles include increasing learning, empowering teams, fostering integrity, removing waste, understanding the whole, delaying decision-making, and quick product delivery.
Extreme Programming (XP)
- Emphasizes speed and continuous delivery in software development.
- Encourages customer involvement, fast feedback, planning, testing, and close teamwork.
- Software delivered every one to three weeks to adapt to changing requirements.
Crystal Method
- Lightweight and adaptable, focusing on the people involved in Agile projects.
- Adapts policies and processes based on each project's unique characteristics.
- Comprises models like Crystal Orange, Crystal Clear, and Crystal Yellow.
Agile Principles
- Twelve core principles guide Agile development, promoting customer satisfaction through early delivery, breaking work into smaller tasks, and welcoming changes even late in projects.
- Emphasizes self-organized teams, support, sustainability, and continuous reflection for effectiveness.
Coping with Change
- Acknowledges that system requirements shift in response to external pressures and technological advancements.
- Agile methods must accommodate evolving software requirements.
Four Core Values of the Agile Manifesto
- Prioritizes individual interactions over processes and tools, emphasizing the importance of people in development.
- Focuses on working software instead of extensive documentation, encouraging an adaptive approach to software development.
Incremental Model
- Development occurs incrementally, adding features in iterations until the product meets all requirements.
Iterative Model
- Starts with a simplified set of user features and gradually expands to include more complexity through iterations.
Rapid Application Development (RAD)
- Developed as a response to traditional waterfall methods, focusing on adaptive software development.
Spiral Model
- Introduced by Barry Boehm, it is a risk-driven model addressing limitations of the waterfall approach.
- Visualized as a spiral with varying loops that represent different project phases.
Kanban Method
- Employs visual workflow management to facilitate product creation with an emphasis on continuous delivery, minimizing stress on the development team.
Dynamic Systems Development Method (DSDM)
- Framework ensuring rapid software delivery, guided by eight key principles including collaboration, on-time delivery, and refusal to compromise on quality.
Feature-Driven Development (FDD)
- Combines software engineering best practices through short-iteration processes, starting with modeling and creating a comprehensive feature list followed by two-week iterations focused on planning, design, and building features.
